Abstract: An ion beam (113) focused into a diameter of at most 0.1 µm bombards substantially perpendicularly to the superlattice layers of a one-dimensional superlattice structure and is scanned rectilinearly in a direction of the superlattice layers so as to form at least two parallel grooves (108, 109, 110, 111) or at least two parallel impurity-implanted parts (2109) as potential barrier layers, whereby a device of two-dimensional superlattice structure can be manufactured. At least two parallel grooves (114, 115, 116, 117) or impurity-implanted parts are further formed orthogonally to the potential barrier layers of the two-dimensional superlattice structure, whereby a device of three-dimensional superlattice structure can be manufactured. In addition, deposition parts (2403, 2404, 2405) may well be provided by further depositing an insulator into the grooves (108, 109, 110, 111, 114, 115, 116, 117) which are formed by the scanning of the ion beam. Owing to these expedients, the portions of the two-dimensional and three-dimensional super­lattice structures can be manufactured with ease and at high precision.

Abstract: According to the present invention, one surface of a temperature compensator (2) is arranged to face the surface of a first electrode (1c) which is formed on one surface of a semiconductor element(1) while one surface of a first external electrode (3) is arranged to face the other surface (2b) of the temperature compensator (2). A second external electrode (14) is arranged in a space region which is defined by a through hole (2a) of the temperature compensator (2) and a cavity (3a) of the first external electrode (3), to face the surface of a second electrode (1b). An insulator (13) is interposed between the outer side surface of the second external electrode (14) and the inner side surfaces of the cavity (3a) and the through hole (2a) so that the second external electrode (14) is located in prescribed positional relation to the first external electrode (3) and the temperature compensator (2). Thus, there is no possibility that any misregistration is caused between the temperature compensator (2), the first external electrode (3), the second external electrode (14) and the insulator (13), whereby the temperature compensator (2) and the second electrode (1b) can be correctly and easily aligned with the first electrode (1c) and the second external electrode (14), respectively.

Abstract: When packaging electrical power cables, consisting of a cable piece on whose one end there is fitted an extruded plug contact, there is a problem in inserting the wire ends into the contact pins arranged on a connector link and the crimping sleeve of an earthing spring. In the past, this was possible only by using manual means. In order to be able to automate this process as well, a retaining bracket extending over the crimping sleeve of the earthing spring is proposed, which has a funnel-shaped insertion opening for a wire end.   <IMAGE>

Abstract: A hybrid relay comprising a mechanical relay provided with mechanical contact unit adapted to be actuated by an electromagnet, an electronic relay consisting of a semiconductor device, and a drive switch for supplying a drive current to said electromagnet, wherein said mechanical contact unit comprises: a first contact mechanism for controlling a load current of said hybrid relay; and a second contact mechanism for controlling a control current for a control gate of said semiconductor device; a contact point gap of said first contact mechanism being larger than that of said second contact mechanism. Thus, it is ensured that the first contact mechanism is engaged after the second contact mechanism and is disengaged before the second contact mechanism. Preferably, the mechanical contact unit further comprises a third contact mechanism, for controlling the leak current of the semiconductor device, which may be provided with a delay mechanism for delaying the returning action thereof. By maintaining the orders of engagement and disengagement of the three contact mechanisms, even when the load of the hybrid relay contains an inductive element, the generation of electric arcs in the first and third contact mechanisms is avoided. The addition of the delay mechanism simplifies the adjustment of the contact gaps of the three contact mechanisms.

Abstract: A position detecting circuit for use in an apparatus for performing position control such as an original read­ing apparatus is disclosed. In the position detecting circuit according to the present invention, emitted light from a light emitting device is received by a CCD image sensor and a peak value of the output signal waveform of the CCD image sensor is detected. Then, the photosensing position of the CCD image sensor is identified according to the position of the peak value in the output signal waveform. The position of a moving member is determined by the photosensing position of the CCD image sensor, whereby the position detecting system is simplified in structure and enhanced in detecting accuracy.

Abstract: The method serves for manufacturing a dental prosthesis comprising a part, such as a crown or the like, for anchoring to the residual denture, and a dental prosthesis part such as an artificial denture, model casting and the like, retained thereon by a detachable connecting device, such as an interlock, lock, screw or the like. To this end, a prefabricated connector having precisely fitting surfaces for the anchoring part and/or the dental prosthesis part and entering into no physical bond with the material of the latter is positioned on a working model representing the jaw situation. The anchoring part and/or the dental prosthesis part made from a model casting compound capable of residue-free combustion is then modelled onto the connector on the working model. A casting mould is prepared from this model, and the connector is directly fixed into the investing compound of the casting mould. The casting of the anchoring part and/or the dental prosthesis part is then cast onto the connector in the casting mould.

Abstract: A data processing system is disclosed for storing and displaying digital images, including a workstation 20 having a document input scanner 22 for digitizing document images at a first resolution, an image display unit 30 for displaying digitized document images at a second resolution which is less than the first reso­lution and a printer 46 for printing digitized document images at a third resolution greater than the second resolution. The system reduces communications traffic and assures fast access time on the network since the bulk of the traffic will utilize the smaller compressed data records required for the second resolution. However, these improvements in communication traffic and access time do not sacrifice the availability of high resolution compressed data records occasionally needed for printing and other high resolution operat­ions.

Abstract: A two-part separable parachute system (12; 12'-12") for a projectile, such as in particular a submunition warhead (11), rotating as it descends into a target area, is to be designed in such a way that the descent chute (14) unfolds satisfactorily after separation of the drag chute (13), initially acting on its own, it being necessary to avoid collisions between component parts remaining attached to the drag chute (13), such as in particular a pack holder (16) and the descent chute (14), having the greater descent/drag effect. For this purpose, the pack tube (18) for the descent chute (14), fastened to the upper sub-system (12'), is equipped with strip-shaped additional drag means (22), which spread out when the descent chute (14) is pulled out from the pack tube (18) and the pack tube (18) is therefore wrapped around in the opposite position by the stream of descent air flowing onto it. <IMAGE>

Abstract: The present invention provides a connector having a seamless tubular metallic shell which not only provides proper RFI/EMC shielding but also is constructed in such a way as to prevent ingress of moulding material into the spaces between contacts of the connector. This is achieved by forming one end of a seamless tube of ferromagnetic material (which is initially of substantially uniform cross-sectional area) such that it is collapsed on to itself and a cable connected to the connector whereby to tightly seal the send of the tube on to the cable to prevent ingress of moulding material subsequently applied to the exterior of the shell. In the case of a cable providing a braid or foil shielding element, this process simultaneously provides an electrical bond between the shell and a portion of the shielding element of the cable exposed by removing a portion of the outer insulation covering of the cable.
